* cache_mngr: add include callback v2Tobias Jungel2016-12-013-1/+12
| | | | | | | | | | | | | | | | | | | | | This patch adds change_func_v2_t to add a more detailed callback in case of a cache change. The change function is registered using the new nl_cache_mngr_add_cache_v2. In case the new change function is set, nl_cache_include_v2 and thus cache_include_v2 will be used to perform the cache inclusion. The parameter of change_func_v2_t are the following: * struct nl_cache * => cache * struct nl_object * => the old/deleted nl_object * struct nl_object * => the new nl_object * uint64_t => the result of nl_object_diff64 in case of a change * int => NL_ACT_* * void * => data https://github.com/thom311/libnl/issues/71 http://lists.infradead.org/pipermail/libnl/2016-September/002214.html http://lists.infradead.org/pipermail/libnl/2016-October/002229.html http://lists.infradead.org/pipermail/libnl/2016-November/002250.html
* lib: use MSG_PEEK by default for nl_recvmsgs()Thomas Haller2016-11-302-1/+17
| | | | | | | | | | | | | | | The MSG_PEEK API of recvmsg() should be avoid because it requires an additional syscall. But worse is to choose a too small buffer size and failing to receive the message. A user who is aware of the issue can avoid MSG_PEEK by either nl_socket_disable_msg_peek()/nl_socket_enable_msg_peek() or by setting a buffer size via nl_socket_set_msg_buf_size(). By default however we now use MSG_PEEK. This is more important since commit 90c6ebec9bd7a where the link dump request can be rather large. Signed-off-by: Thomas Haller <thaller@redhat.com>

* xfrm: remove unused struct xfrmnl_sec_ctx from header filesThomas Haller2016-11-061-9/+0

* xfrm: fix xfrm security context managementThomas Egerer2016-11-062-1/+9
| | | | | | | | | | | | | | | | The data structure of choice when adding/processing a security context for xfrm is struct xfrm(nl)_user_sec_ctx. The previous code did however use the (also exported) struct xfrm(nl)_sec_ctx. While sizeof(struct xfrm(nl)_*sec_ctx) yields the same result, the interpretation of one of the data structures as the other one messes up the contents. With this fix, the wrong data structure has been replaced with the correct one. Also -- since the size of the context string is not known -- one can now call xfrmnl_sa_get_sec_ctx with ctx_str being NULL, thus retrieving the length of the context string. A new capability has been introduced, to test whether libnl3 supports the modified semantics of this function. Signed-off-by: Thomas Egerer <thomas.egerer@secunet.com>

* vxlan: refactor setting/getting vxlan flagsThomas Haller2016-11-051-8/+2
| | | | | | | | | | | | As these properties are FLAG types in the netlink API, we should also expose them as such in the libnl API. It is less code and require less code to support a new flag. The point is really to keep the API smaller instead of wasting a getter and setter for each flag.
* vxlan: don't store vxlan flags as ce_maskThomas Haller2016-11-051-0/+9
| | | | | | | | The ce_mask is there to indicate whether a certain attribute is set or not. The VXLAN flags are different, because the flag is either set or not. It cannot have the meaning of being missing. Therefore, it should not be stored as a VXLAN_ATTR in ce_mask.
* vxlan: remove redundant enable/disable API from vxlanThomas Haller2016-11-051-18/+0
| | | | | | | | | The enable/disable API is redundant and increases the library in binary size and documentation. There should be one sensible way to do something, not several. Yes, there is prior act to that like rtnl_link_vxlan_disable_proxy(). That doesn't mean it should be repeated.
* vxlan: add support for additional VXLAN attributes.Brandon Carpenter2016-10-302-5/+236

In particular it adds the following attributes: * IFLA_VXLAN_PORT, * IFLA_VXLAN_UDP_CSUM, * IFLA_VXLAN_UDP_ZERO_CSUM6_TX, * IFLA_VXLAN_UDP_ZERO_CSUM6_RX, * IFLA_VXLAN_REMCSUM_TX, * IFLA_VXLAN_REMCSUM_RX, * IFLA_VXLAN_GBP, * IFLA_VXLAN_REMCSUM_NOPARTIAL, * IFLA_VXLAN_COLLECT_METADATA, * IFLA_VXLAN_LABEL, * IFLA_VXLAN_GPE https://github.com/thom311/libnl/pull/110
* macvlan: adjust types and merge MACVLAN_HAS_MACCOUNT and MACVLAN_HAS_MACDATAThomas Haller2016-09-271-1/+1
| | | | | | | | | | | | | | | | mvi_maccount only makes sense together with the data. They should be treated as one setting, and both should be consistent. That means, if there are no addresses, mvi_maccount should always be set to zero. This is regardless of whether the mvi_mask indicates that MACVLAN_HAS_MACADDR is set. Similarly, if mvi_maccount is larger then zero, the mvi_macaddr must point to some valid addresses. The only exception is, when mvi_maccount is zero, mvi_macaddr may be NULL or point to some data of zero allocated bytes. Also, ensure that uint32_t is used for all the types that compare with mvi_maccount. Signed-off-by: Thomas Haller <thaller@redhat.com>

* lib/route: Support IFLA_BRIDGE_MODEJef Oliver2016-09-241-0/+13
| | | | | | | | | | | | | | | | | | | | | | | This patch adds support for hardware assisted bridge modes stored in IFLA_AF_SPEC[IFLA_BRIDGE_MODE]. This patch adds rtnl_link_[g/s]et_hwmode() functions, allowing for getting and setting the hardware mode for a bridged link. This patch adds the convenience functions for translating between integer and string names for hardware modes. This patch adds rtnl_link_bridge_set_self(), a function that stores flags in IFLA_AF_SPEC[IFLA_BRIDGE_FLAGS], an attribute that tells the kernel whether it should apply settings to the virtual bridge device or the hardware device itself. This requires hardware that supports the hardware flags. This patch adds bridge_fill_af(), a function to fill IFLA_AF_SPEC with AF_BRIDGE specific information.

* lib/route: Allow override of IFLA_AF_SPEC nestingJef Oliver2016-09-241-0/+8

Regular Nesting: [IFLA_AF_SPEC] [AF_INET] [AF_INET_ATTRS] Bridge Nesting: [IFLA_AF_SPEC] [AF_BRIDGE_ATTRS] This patch adds ao_fill_af_no_nest to struct rtnl_link_af_ops.

* lib/route: set IFLA_PROTINFO attribute in request messageJef Oliver2016-08-291-0/+13
| | | | | | | | | | | | | | | | | | | | | | | This patch adds the functionality to set IFLA_PROTINFO in a request. This allows for appending protocol specific information to a request message. This patch adds ao_fill_pi to the rtnl_link_af_ops structure. This registers a function to fill the IFLA_PROTINFO attribute. This function follows the makeup of ao_fill_af. This patch adds ao_fill_pi_flags to the rtnl_link_af_ops structure. This registers an extra flag that can be bitmasked onto the IFLA_PROTINFO definition. This is useful for address families that require NLA_F_NESTED. This patch adds a function named af_fill_pi, which is called by build_link_msg. This function calls the registered function pointers for an address family to fill IFLA_PROTINFO and to bitmask any extra flags.

* lib/route: allow override of message type during link changeJef Oliver2016-08-291-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | When rtnl_link_build_change_request() builds a change request, it sets the message type to RTM_NEWLINK by default. If the request fails, it changes the type to RTM_SETLINK, and resubmits. For some address families, this will result in a requested change never being applied by the kernel. An exmaple of this is the Linux bridge. When a netlink message of type RTM_NEWLINK is recieved, rather than failing, it simply ignores the message and does not return a failure. To fix this, this patch implements an override for address families that require it. The override can be set when an address family registers itself in libnl. This patch adds ao_override_rtm to the rtnl_link_af_ops structure. This patch adds a static function named af_request_type. This patch modifies rtnl_link_build_change_request to call af_request_type to properly set the request type if an address family wishes to override.

* lib: add utility function nl_strerror_l()André Draszik2016-08-252-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libnl currently uses strerror_r() throughout, but this is problematic because there is a non-standard GNU version implemented in glibc, and the standard POSIX version, which differ in signature. When using glibc, one can choose between the two versions using feature test macros _GNU_SOURCE and _POSIX_C_SOURCE. Given libnl is built using the former, we always get the glibc special version, and all code so far has been written for that non-standard version. Other C libraries like musl on the other hand only try to be posix compliant, and only ever provide the posix version of strerror_r(), which has a different signature. The alternative is to use strerror_l() rather than strerror_r() http://austingroupbugs.net/view.php?id=655 - this will avoid the non-confirming versions issue - strerror_l() is now recommended by POSIX to replace strerror_r() usage So rather than changing all uses of strerror_r() to be in line with posix, we are going to switch to the recommended interface strerror_l(). Since strerror_l() is slightly more difficuly to use, we add a little (private) wrapper that we can use from all current callsites of strerror_r().
